A1.The molar volume (cmmol) of a binary liquid mixture at T and P is given by: V=120X +70X+(15X +8X2)X a. Find expressions for the partial molar volumes of species 1 and 2 at T and P. b. Show that when these expressions are combined in accord with M = X,M, the c. Show that these expressions satisfy the Gibbs-Duhem equation (X,dM = 0). given equation for V is recovered. d. Show that (dv/dX)x- = (d / dX)x-0 = 0. e. Plot, using a graphing software, the values of V, V, and V, calculated by the given equation for V and by the equations developed in (a) vs X. Label points V1, V2, , and 2, and show their value. Note: example 11.3 in the textbook might be helpful for this problem.
